APPAmiTus` y Appncatioa md August' 16,1929.` serial No. 386,338.

\ My invention `is a machine for filling shoes and relatesto the filling of4 shoe-bottoms with plastic filler of the kind `which is deposited y and spread inthe shoe-bottom cavity by hand A '5 tool or spatula resembling a trowel. While this machine is intended for handling any of the known kinds of Commercial, spreadable `filler, hot or cold, such as those disclosed in my numerous filler patents, itiA is especially M adapted "to handle cold plasticffiller, particularly` ofthe dispersed ,binder kind both cold and hot dispersion and othe'rplasticfillers somewhat analogous thereto which, as well known, are quite diicultito manage properly because oftheir free flowing character `whichfis lost quickly 4because of the rapid evaporation. On account of the` dif4 ficulties as to evaporation et'candalso because of the growing requirements of modern i @practice `for continual increase in speed of' filling slices, `my invention has for` a further "object the facilitating of Speed ingfilling e shoes.` l It also promotes neatness and economy.` In Vcase of'highlyevaporable fillers it i ,25 reduces to a minimum the loss by evaporation.

Using theV last mentionedktype offiller for purposes of'illustration, the machine in its simplest embodiment consists of a `conditioning chamber forholding and Atempering or maintaining in rproper temper `thedesired bulk or mass ofthe loose filler, and working `shelfor tableV for receiving segregated `portions of the filler from said chamber` 1in `amounts only enough each time for agsingle shoe or at the most for `two'or three or a few a templet having one or more `openings for delivering the filler into theshoebottom cavity. The templet and the shoebottom "cavity are maintainedrelatively stationary while the filler is deposited therein in predetermined sheet form. This constitutes one of the main features of my invention. Another .i main feature of my invention is providing means for determining the shape, `thickness e and amount of the filler mass to be deposited insaidr cavity and yfor so maintaining j` the `same until actually deposited in the cavity. `Also in the preferred embodiment'of my iny 50 vention 'one of the radically new features is the provision of means for, automatically predetermining the amount of `filler for the shoe bottom cavityl and delivering said amount thereinta' In other words, although han `dling soft fluid filler, my machine determines the shape and then maintains said shape ofthe filler mass until actually in the shoe in properl-y deposited position, also it similarly determines the amount deposited, determines the shape and thickness,and likewise it delivers this soft and ordinaryunmanageable filler into the shoe as a sheet-like layer. In each lof the foregoing respects my present inven` tion is broadly new. Preferably the templet is made of spring material normally curved.

slightlydownward so that when the operator `placesan upturned shoe-bottom (on the last) against-the underside thereof ,with the bot- .tom cavity aligned with the filler delivery opening and l presses `the `shoe-bottom; up- `ward,the` spring templetwill yield until it conforms exactly to thereverse curvature of `the `shoe-bottom, and, because of its spring character, will press down in tight, close `contact withthe shoe-bottom all around the bottom cavity of the Shoe. Most shoes have ,slight'eurvatura being almost flat, whereas other shoes have considerable curvature, and

athis spring-like yielding table with its delivery orifice causes the instant automatic,4 i Atight adjustment of the delivery orifice "all i around the cavity which is to be filled. I-Iaving placed the shoe-bottom (on its last, of

y course) thus in position the operatorwith his -handitool or spatulaslides a small heap of shoes. `This table or shelf is inthe form of filler from the chamber or from the ledge forward and wipes it into the shoe-bottom cavity l,through the opening and with a single sweep ofthe tool or knife levels it even with the top surface ofthe templet around `the edge of the opening. Thethickness of the edge of the opening determines theramount of filler deposited `in the shoe-bottom and deter-` mines its height above the-,top level of the `boundary of `theishoe-bottom cavity. As it is `impracticable and in lfact impossible to smaller and then depend upon the thickness of the templet at the edge of the opening to determine the surplus filler or additional height of the smaller deposited layer which is necessary for the subsequent spreading of the plastic filler in order fully and correctly or exactly to occupy the entire cavity in proper relation to the outsole whenever laid.

To facilitate the positioning of the shoe with relation to the filling table or delivery templet, a positioning support, preferably a roller, is provided for supporting the toe 0f the shoe, preferably yieldingly, so as to permit the operator to place the toe thereon readily and then tip the shoe and its last upward endwise on the toe as a fulcrum until the filler opening and `bottom cavity have been brought into the exact juxtaposition desired. If desired this filler delivery opening or oriiice of the templet is made adjustable for different sizes of shoes and shapes of bottoms. My invention however is primarilyl intended for the filling of McKay shoes and as only about three different sizes of filler delivery openings are required for this kind of shoe, I prefer to provide the table or templet with the three separate openings.

As already stated, my invention is broadly new and accordingly it is capable of a wide range of embodiments, two being herein presented to illustrate the carrying out of the invention in a more automatic manner and in a more rapid manner. Instead of the spatula or other hand tool I provide in one embodiment a rotary tool, power driven, and in another embodiment a reciprocating tool preferably under the control of the operator. It will be understood that all the embodiments herein shown are illustrative, to make clear the broad scope and radical advance of this invention. Y i

The conditioning chamber 1 may have the general shape shown in my Patent 957,393 dated May 10, 1910 excepting that it has a heavy top 2 for keeping the top of the chamber 1 continually sealed, (except for filling or loading with filler) and is provided with a stop 3 adjacent the hinge pivot 4 for preventing the operator from accidentally leaving the top open. At the lower front end of the chamber is an opening 5 which may be' closed by a slide door 6 working in guides 7 as the door or regulating valve 6 is raised or lowered by the operator by means of a handle 8. At the forward edge of a ledge 9 and extending therefrom to a supporting frame 10 I provide a member 11, preferably of yielding or spring sheet material, which constitutes the templet mentioned, shown in top plan view in Fig. 2 as provided with three delivery orifices 12, 13, 14, respectively, of dif-v ferent sizes conforming somewhat to the approximate shapes of shoe cavities. If the filler being used requires heat the templet is made of metal so as to retain some of the heat, but if restricted to cold filler it may bev made of transparent material such as celluloid, thereby further facilitating speed by enabling the operator to see how he is positioning the shoe. The spring templet 11 is preferably mounted in a slotted frame 10 extended at its ends 15 from the ledge 9. This rigid strong construction is necessary for proper strength and also advisable for conveying and storing moderate heat in case the machine is built for hot filler. Mounted belo-w the ledge 9 are toe rests or supports in the form of rollers 16, 17, 18 which constitute fulcrums and also guiding and shoe-positioning members. These rollers are preferable instead of more stationary supports because it is necessary not to mar the more or less delicate leather of the toe of the shoes being filled and therefore the rolling movement of a roller is preferable. Also the rollers preferably have soft coverings 19 of rubber,

` cloth, leather or the" like and are mounted on movement on posts 21 by means of springs end bearings`2()` and give limited vertical 22`which tend normally tomaintain them in upward position and yet permit downward yielding Whenever required by the particular style orspring of the shoe.` Preferably each "wires 27 indicated as in roller has a hollow or directing and centering curve 23 `for automatically bringing the toe into alignment with the opening thereby aiding the operator in the proper positioning of the shoe-bottombeneath its filler opening.

` In case it ispreferred to use an adjustable `templet opening instead of having a templet `provided with several fixed openings as shown in Fig.` 2i, I providethe same in any convenient manner, as for example shown in Figs?) and 4. The opening 28 is provided by four bladesor separate portions 29,30,

3l, 32 of the templet. Eachblade is `shown as overlapping at one end the next blade so as to make aclosed peripheral opening 28 to prevent any filler going through the templet at any place except the opening 28; The four "movable `plates are held adjustably` in a i grooved frame 33. Thus if alarger opening 28 is desired, the operator separates the plates by pressing outwardly at the opposite longitudinal middle edges which causes the plates 29V and 30 to pivot or swing on each d other at their meeting points 34.

i Before explaining the other embodiments of my invention, "I will set forth the use of the more simple apparatus just described. The operator raises the heavy top 2 of the cham- `p ber 1 and dumps into the latter `a quantity of the filler, the highly volatile or evapora-ble and changeable filler, let it be supposed. The heavy top falls and sea-lsin the mass of `Ifiller against rapid evaporation or change.

He then raises the dooror closing device 6 sufiiciently to permit him to` poke out onto the ledge 9 by means of his spatula 24 such amount of filler as he desires. IIe now takes al shoe, on its last, from the rack and quickly places it bottomside up with the toe on the `readily turning positioning-roll V16 and slidesthe same fo-rward until it is properly beneath theopening 12 for example, andat once raises the shoe-bottom forcibly upward latter is level or bent upward still further to iit the; curve of the upturned shoe-bottom. The skilled operator accomplishes all this by thesingle forward thrust of the shoe in his left hand. He simultaneously places the toe on the roll 16 as a support and fulcrumand raises the heel and thereby swings the shoe- `bottom forcibly upward against the spring bottom or templet 11 until the latter has conformed itself into close peripheral engagement with the inturned edges of the upper,

leaving the filler delivery opening 12 properly centered with thebottom cavity of the sliding sweep of the spatula blade 24 over the ,opening 12in Contact with the edges thereof. t The operator judgesfrom the size of the shoe-bottom cavity and the shape and i depth thereof whether to use the large opening 12 or the4 small opening 14 or the intermediate opening 18.` The edge thickness ofV the 'opening determines the height of the fill-` er layer as deposited and left in the shoebottom at this stage of the operation. This is important as it determines automatically the amount of filler deposited, orlmeasures, as it were, the requirements `of the shoe. Heretofore it has usually been the case that theloperator, without anysuch regulating mechanism, would either get too much filler 1into the cavity thereby necessitating brushing it off fromtheshoe andtherefore soiling the Aadjacent parts of the shoe, or else he would not deposit quite enough filler in the shoe-bottomcavity. In the latter 4ease a careless-operator would leave the cavity improperly filled or the more careful operator would be delayedby having to pick up. the needed further amount of filler and place it in the shoe-bottom. Having thus delivered the exact amount `of filler into the shoe-bottom cavity as determined automatically by the opening 12 and the method of use exlained, and levelled the same as atrue and exact sheet-like layer by the single sweep of his spatula asstated, the operator withdraws the shoe and either runs itunder a usual spreading" roll or accomplishes the same spreading by a further stroke :of his spatula blade 24 over the shoe-bottom, thereby spreading down to the level of the invturned upper `and outward into filling'relation with the entire cavity, the layer of `filler as previously leftproj ecting by the templet opening 12. This will all bemore readily understood by viewing- Fig. 7 wherea shoe upper 35 is shown on its last 86 with its inturned edges 37 forming a usual bottom eavity 38 in the middle of which is shown a deposited layer 39 of filler resting on the innersole and whose lateral size is determined by the edges of the opening 12 in the templet 11 and whose height above the depth of the cavity 38 is determined by the thickness of the templet 11 at said edges. The operators spatula blade 24 has swept the iller into the form of a sheet-like layer 39 exactly level with the top surface of the templet 11. Vhen therefore the shoe and its last are withdrawn this upstanding or projecting layer 39 is brought by a sweep of the operatorfs spatula blade 24 level with the inturned edges 37 of the upper and simultaneously spread later-y ally and in whatever direction required to fill the bottom cavity 38 completely.

In Figs. 8-14, I have shown a rotary depositing mechanism. The table or templet support is shown as the bottom 41 of a shallow pan or holder 42 for the small amount of filler withdrawn from the tank or supply reservoir 1 (small when the evaporable or rapidly changeable type of filler is being used) and mounted in this pan or filler holder is one or more movable members 43 herein shown as two, pivotally supported on trunnions 44 in a rotary post 45 journaled in a frame or spider 46 and 'rotated byV any suitable means as by a pulley 47 and belt 48. These movable members or tools perform the office of the spatula 24 for scraping or moving the soft Vmushy flowable filler quickly into the template opening and levelling it olf the same as before explained. A templet 49 is shown having an opening 50 and an auxiliary toe rest 5l, said opening being indicated in Fig. 8 as already filled with a layer 52 of the plastic filler. Preferably the depositing tool 43 is given substantially the same movement that'the operator gives the spatula 24. It not only slides the filler forward but presses it down into the opening of the templet so as to make certain that the filler is not slid forward and more or less of it out again past the templet opening. This Hopping or swinging movement of the blade 43 may be accomplished in many ways, the means illustrated consisting of a triangular trip 53 fast on one end, shown in Fig. 8 as the outer end of each blade or filler mover 43 in position to engage fixed cams 54, 55 on the inner lower portion of the wall of the pan 42. Asa blade 43 moves forward in the direction of the arrow 56 Figs. 9 and 11, its trip 53 is in the position shown in Fig. 14. When it meets the rear end of thecam 54 the lower point or corner 57 (also see Figs. 13-14) strikes the adjacent end of the cam 54 and is thereby turned into the position shown in Fig. 13 so that its flat side 58 rides on the top flat surface of said cam 54. This flops or tips over the blade 43 from its upright position into a slanting position and tends to press downward whatever mass of the loose filler has been shoved along ahead of it as it rotated toward the templet opening.

Having filled and pressed down the filler v(and with certain types of fillers compressed ythe same) so as to fully fill and level o' the templet cavity the now upper end 59 strikes lthe cam 55 which operates to turn the blade vtemplet opening. This tends to condense and entirely ll the lopening to its full capacity. As the shoe filling operative relieves the'pressure on the auxiliary toe rest 51 the templet 49 slides rearwardly toward said operative and the front of the machine in its ways 61, being actuated by any convenient means, herein shown as actuated by a weight 62 whose cord 63 is secured at 64 to a stationary part, said cord passing over a pulley 65 mounted -in the far end of a slide plate or bottom closure 66 which abuts against the forward end 67 of the templet plate y49, so as to move with the latter. Thus when the shoe is withdrawn and thereby the templet moves to the left from its position in Fig. 8 the space in the bot-tom of the pan which had previously been occupied by the open portion 50 of the templet is closed automatically by the closing plate 66 as shown in Fig. 9..

In Fig. 15 I have shown an embodiment of vmy invention in which the operation of the filler-depositing mechanism is reciprocal instead of rotary as last described. Projecting forward from the tank 1 is a bottom or table 68 provided with a templet 69 in line with the filler delivery opening 5 and door 6 the same as in the previous constructions, sides 70v and wings 71 being preferably provided for holding the filler which the operator pokes out from the tank. A depositing and levelling tool 72 is mounted on a carrier 73 operated by any suitable means, herein shown as a handle 74 to swing back and forth over the templet opening 75 in the templet 69. Said levelling tool may be of any convenient shape, herein shown as flat on its underside to cover the opening 75 and slanting therefrom at 76, 77, for pressing the filler downward in the same way that a hand spatula is used. For poking the filler forward into the opening 75 and in position for the levelling tool to spread and press the same into said opening and level it off, I provide side wings, Scrapers, or filler movers 78. 79 movable with the carrier 7 3 and tool 72. Preferably wings 8O project laterally outward from said Scrapers or filler movers to prevent the possibility of any filler dropping from the tank behind one or the other of the Scrapers or llO ' 1o.` e e dicated at 83Aheating means for the applying l tool toprevent the filler from sticking theretoand to speed up the relative movement and shoe filler Workman from to maintainthe filler properly melted or `fluid jfor` quick delivery.` "lhese Walls 82 cooperate fvviththe wings 71 to form a sort `.of hopper for the filler asthe flatter is poked bythe the tank intojthe Work basin or onto the table `68. In use, the

The
